I disagree. The article is making claims about software renderers of the time vs hardware accelerated renderers of the time, as they typically worked. It's missing the point completely to believe the author of a blog seemingly dedicated to old games and old hardware is making a general claim about software renderers and GPUs as understood now. Context matters!

The author didn't qualify every word he wrote with "of the time" and "typically", possibly because he didn't expect their article to be nitpicked on HN, but a cursory reading shows that's what he meant.
